Abstract
A metal gate and high-k dielectric device includes a substrate, an interfacial layer on top of the substrate, a high-k dielectric layer on top of the interfacial layer, a metal film on top of the high-k dielectric layer, a cap layer on top of the metal film and a metal gate layer on top of the cap layer. The thickness of the metal film and the thickness of the cap layer are tuned such that a target concentration of a cap layer material is present at an interface of the metal film and the high-k dielectric layer.
